1.4 Major Components
The operating principle of the UPS is shown in Figure 5.
Figure 5 Operating principle diagram
The UPS is composed of mains input, TVSS and EMI/RFI filters, rectifier/PFC, inverter, battery
charger, DC-to-DC converter, battery, dynamic bypass and UPS output.
Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters
The Liebert GXT3 has surge protection and filters that protect the connected load from power surges
and sags, electromagnetic interference (EMI) and radio frequency interference (RFI). These features
can minimize any surges or interference present in the mains power. The filters also prevent surges
or interference generated by the UPS from adversely affecting other devices connected on the same
branch as the UPS.
